Abstract

For level 2 remote sensing data of CBERS-02 satellite, polynomial model is usually used in geometric precision

correction. Compared with polynomial model, rational function has higher precision in hilly or mountain areas. With the

mountain area in northwest Gansu Province as an example, the authors compared and evaluated the results of two models

applied to geometric precision correction. For an area with elevation over 4 000 m, the precision of rational function is

2~3 times higher than that of polynomial model.
